Stansfield, Kate, Smeed, David A., Gasparini, Gian Pietro, McPhail, Stephen, Millard, Nick, Stevenson, Peter, Webb, Andy, Vetrano, Anna and Rabe, Benjamin (2001) Deep-sea, high-resolution, hydrography and current measurements using an autonomous underwater vehicle: the overflow from the Strait of Sicily.

AUTOSUB-2, an autonomous underwater vehicle (AUV) developed by the Southampton Oceanography Centre, was used for high resolution hydrographic surveys in the Sicily Strait. A combination of "seasoar" type profiling and terrain following missions were undertaken and velocity and hydrographic measurements taken from AUTOSUB-2 were compared with concurrent shipboard hydrographic and velocity profiles. Even though shipboard stations were separated by just 5 to 8 km along the mission path, data from the AUV showed small scale variability that was missed by the shipboard sampling. In this paper we present the example of an intense jet, with maximum speed greater than 0.50 m s-1, less than 4 km wide.
